I have two HDDs. I have done a clean install of W8.1 using a brand new MB.
Both HDDs are listed in the BIOS and Device Manager but only the one for the OS in "This PC" (which I suspect was known as "My Computer".
I suspect I may have cleaned out the missing one during the OS install.
I see that a missing HD issue was around with 8.0 around about a year ago and a registry change needed to fix, but what is the latest please.
I have a backup of the data that is needed on the missing drive.
 

Check in Disk Management (Winkey plusX )
Should see it there, Rt click to activate the drive. (Assign a drive letter etcetera)
